Abstract
The utility model discloses a fire -proof expansion seal strip for the installation emergency exit is all around in the crack, when meeting heat around the inflation seals the door rapidly gap of expandable sealing strip when meeting the fire, prevents that heat and smog from scurrying into. The sealing strip is including inflation body layer, self -adhesion glue film and decorate the protective layer, sets up the rectangle that can imbed inflation body layer or conical protruding on decorating the protective layer internal surface, and bellied height is 0.5mm~1.0mm. It is the same with the inflation body layer material to decorate the protective layer, and the compatibility is good, decorate protective layer and the inflation body layer calendering molding when an inflation body layer temperature reaches VICAT softening temperature, density is big, and the inflation multiplying power is high, reaches 20~25 times, and it can expand rapidly to meet heat chance fire, and the fire prevention that keeps good separates cigarette, thermal -insulated effect, sets up the arch on decorating the protective layer, decorates protective layer and inflation body layer contact surface and adopts convex -concave interlacing structure, and increase substantially decorative layer and inflation body laminating close the area, have strengthened peel strength, long service life.
Description
Technical field
This utility model relates to fire proof seal product technique field, particularly relates to a kind of fire proof sealing strip with decorative layer.
Background technology
In order to realize the fire-proof function of safety door, the method adopted at present is usually in safety door surrounding crack between a door and its frame and installs expanding sealing strips, when heat meets fire, expanding sealing strips expands rapidly closing door surrounding gap, prevent heat and smog from scurrying into, guarantee the person and life security, win the quality time for personnel escape.Fire-proof expansion seal strip is generally made up of expander, self-adhesive and decoration protective layer three part; expander heat expands rapidly the gap of opposite house and has sealing process after meeting fire; self-adhesive is used between expander and door body conveniently, firmly pastes; decoration protective layer can need arbitrarily to change surface color, decorative pattern and pattern according to user; so as to adapt with surrounding and decoration style, reach the effect of attractive, decorative.
The fire-proof expansion seal strip of currently available technology is generally adopted common skill extrusion molding or two kinds of processing technique of cold moudling; coextrusion forming process adopts the mode of production of two co-extrusions; namely it is a die swell body; another extrusion decoration protective layer; the fire-proof expansion seal strip density of this explained hereafter is little; expansion multiplying power is low, is only 2.5～3 times, and it is bad that heat meets fire Expansion sealing effect.Main prominent functional and have ignored aesthetic property and color is single；Cold pressing forming process is exactly that the shortcoming of the fire-proof expansion seal strip of this explained hereafter is that peel strength is low, it is easy to peeling, bonding insecure extruding sheet of expander and the mode machine-shaping of decoration protective layer used laminating of colding pressing.
Utility model content
The technical problems to be solved in the utility model is to provide the fire-proof expansion seal strip that a kind of expansible fireproof is effective, decoration protective layer and expander are firmly combined with.
The technical solution adopted in the utility model is: a kind of fire-proof expansion seal strip, including expander layer, self-adhesive glue layer and decoration protective layer, arranges the projection that can embed described expander layer on described decoration protective layer inner surface.
Further, the projection on described decoration protective layer inner surface is rectangle or cone；Protruding height on described decoration protective layer inner surface is 0.5mm～1.0mm；Described decoration protective layer is identical with described expander layer material, adopts extrusion calendaring technique, when described expander layer temperature reaches Vicat softening point by described decoration protective layer and described expander layer one-step calendering formation.
The beneficial effects of the utility model are: decoration protective layer and expander layer adopt the material with material, and the compatibility is good；Adopt extrusion calendaring technique; to decorate protective layer and expander layer one-step calendering formation when expander layer temperature reaches Vicat softening point, density is big, expansion multiplying power is high, reaches 20～25 times; heat is met fire and is expanded rapidly, keeps good fire prevention, every cigarette, effect of heat insulation.Arranging projection on decoration protective layer, decoration protective layer adopts convex-concave cross structure with expander layer contact surface, increases considerably decorative layer and expander layer fitting area, enhances peel strength, long service life.
Accompanying drawing explanation
Fig. 1 is the first embodiment rectangular preiection generalized section of this utility model；
Fig. 2 is this utility model the second embodiment conical protrusions generalized section.
Detailed description of the invention
As shown in Figure 1; the first embodiment fire-proof expansion seal strip of this utility model; including expander layer 2, self-adhesive glue layer 1 and decoration protective layer 3; on the inner surface that described decoration protective layer 3 contacts with described expander layer 2; setting can embed the rectangular preiection 4 of described expander layer 2, and the height of rectangular preiection 4 is 0.5mm～1.0mm.
As shown in Figure 2; this utility model the second embodiment fire-proof expansion seal strip; including expander layer 2, self-adhesive glue layer 1 and decoration protective layer 3; on the inner surface that described decoration protective layer 3 contacts with described expander layer 2; setting can embed the conical protrusions 4 of described expander layer 2, and the height of conical protrusions 4 is 0.5mm～1.0mm.
Product thickness and width can require customization according to user, and decoration protective layer adopts identical material with expander layer.Adopt extrusion calendaring technique, will decoration protective layer and expander layer one-step calendering formation when expander layer temperature reaches Vicat softening point.Properties of product meet or exceed GB16807-2009 fireproof expansion seal part standard.
Claims (5)
1. a fire-proof expansion seal strip, including expander layer, self-adhesive glue layer and decoration protective layer, it is characterised in that arrange the projection that can embed described expander layer on described decoration protective layer inner surface.
